To all whom it may concern: j l I Be it known that I, Jenn YVALDHnrM, acitizen of thellnited States,.residing in Elizabeth, in the county ofUnion and State of New Jersey, have invented, certain new and usefulImprovements} in Typewritinglvlachines, of which the following is aspeci tication. Y

li ly invention relates, chines of the class wherein a plurality ofseparate and distinct printing mechanisms or devices are provided, anyone of which may be operated by a single set-of key levers and from asingle key-board, so that a plurality of tents of type differing instyle troin one another, or fonts of type adapted for writing in two ormore languages, are available for use in the same machine the machinebeing capable of adjustment in such a way that any one of the printingmechanisms may be used at will." The object of my inventionis to providecertain improvements in; machines of this type, and wherein theprintingdevices; are unitary structures insertible into and removablefromthe machine as a Whole and at a single operation, whereby the numberof kinds or styles of fonts oftype'usable in a particular machine isunlimited; this in vention' being an; improvement upon the typewriterdisclosed in'my' co-pending" application filed March 20, 1918, l\o..223,489, v A plurality of printing devices, preferably in the form oftype-sets, compriseeach' a type-bar. supporting segmentcarrying aplurality of pivotally supported type-bars, the said printing devicesbeing supportedin fixed relationto oneanother by 'a movable, membersupported from the frame of the machine; said printing devicesbeingreadily detachable as a whole and as unitary structures from themovable member whereby they, are supported, so that any one or all ofthem maybe removed from the movable member and other printing devicessubstituted therefor; thus providing for the'use of. any number ofprinting devices and any number, of stylesor kindsof fonts or type in asingle machine. y

The movable supporting member provides for the movement of any one oftheprint ing devices,which maybe supported by it at any given time, into aposition such; that it will'typewrite properly upon a work-sheet totypewritingmasupportedfby a carriage carried by the ma-C chine,;"all theprinting devices being adapted to printat .one and the same point; and

'means are provided for locking the movable member in positionssuch thatanyone of the printing devices carried thereby will be roper positionfor, typing upon the wor esheet.

The movable support ng member erably in the-form or a barmovable in thedirection of itslength along suitable guides carried by the frame'o'fthemachine; and the said bar carries brackets whereby the, printingdevices are supported, and the construction of which brackets is suchthat any prlnting device may be readily removed from the machine andanother substituted therefor. Said bar is also provided with a ribhaving notches orrecesses spacedapart from one another and adapted tobeengaged by a swlng'ing locking pawlto thereby lock the bar inpositions suchthat theiprin'ting device selected for usevwill printproperly upon the work-sheet; the, end portions of said rib being higherthan the middle portion and forming stops forlimiting the normalmovement of the bar. The locking pawl may, however, be swung into anex-i treme position in which it will clear the end portions of the rib,thus permitting a furth'er movement of the bar in order to carry thetype-sets supported thereby beyond and free fromthe frame ofthe machineto thereby facilitate their f removal from the supporting bar, andin'order that the frame may not interfere with the substitution of oneprinting device forv another. 1

Each printing-device preferably comprises an upper type-barv supportingsegmentwhereby a plurality of type-bars are pivotally supported; i alower crossb'ar whichserves'as'a support for a plurality of pivotallyu.supported typebar operating members operatively connected one with eachof said bars and connectingside portions whereby said cross-bar andsegment are connected together, whereby a unitary type-set, removable,in its entiret' andjas a single structure from the movab e supportingbar, is provided; the side portions of the r type-sets carrying meanswhereby they are supported from the brackets carried by the bar in sucha Way as to be readily detach able therefrom.

A single setof keylevers is provided foroperating all of the printingdevices with which a machine may be equipped or which may beused'therewith, said key levers be ing provided with means whereby theymay be'operatively Connected with any particular printing deviceselected for use. In the embodiment of my invention illustrated, the keylevers are provided each with a connecting member pivotally connectedtherewith, and the free ends of the-connect ing members are providedwith pins adapted to be moved into and out of engagement with slotsformed in the type-bar-operating type-set and unlock the movable bar,whereby thetype-sets are supported, thus leaving the bar and type-setscarried thereby disconnected from the key levers and unlocked from theframe of themachine, and free to be-moved to bring another type'set intoposition for use. i 1 i i A single escapement mechanism is provided, thesame being supported from the -main'frame of the'machine and operativelyconnected with the carriage thereof. Each type-set, however, is providedwith an individual universal bar, and the single escapementmechanism isoperated by the universal bar of the particular type-set in use at agiven t me; motlon'bemg transmitted from the universal bar to the dogsof the 'escap'ement mechanism through a reciprocating pivotally"supported inter mediate member adapted to be engaged by any oneofsaiduniversal bars, and which in turn is'in engagement with the dogs.

Suitable mechanism for supporting and advancing a'ribbon, and for'shifting'a por-' tion thereof in unison with the platen as v the sameis moved into its upper and lowercase positions, will also be provided;the ribbon mechanism comprising vertically shiftable ribbon-vibratingmembers carried one by each of the type-sets'and adapted to move theribbon into the path of a type as it approaches the platen, togetherwith operating levers, one associated with and adapted to. operate eachribbon-shifting member; the said lastmentioned levers being carriedbythe platen-shifting mechanism, and motion being communicated to themfrom the universal bar of the particular type set in use at a given timethrough operating lever being thus always associated with its owntype-set and 'operatively connected with the ribbon-vibrating memberthereof, although only the lever and ribbon-shifting member associatedwith the type-set in use at a given time are then in actual operation;one only of said operating levers being connected with and operated bythe said reciprocating intermediate member at the time in question.

In order to provide for the convenient and ready removal of thetype-sets from the machine as unitary structures, the connectionsbetween the ribbon-shafting members carried by the type-sets, and thelevers which operate the same and which are permanently associated withthe machine, are made readily separable as the type-sets are removed,preferably by providing a slot at the free end of each operating leverinto which a pm at the lower end of the ribbonshi'fting members mayenter. The typesets as a whole are supported from the movable bar orother supporting member whereby they are carried by brackets earmemberried by the bar and having slots adapted to receive pins carried by theside members ofthe type-sets, a suitable locking member or devicebeing'provided for locking each type-set to the supporting member towhich it is secured and whereby it is carried.

"Other features andv advantages will hereinafter appear.

In the accompanying drawings,

ig. 7 is a fragmentary view illustrating ent type-set. icferring to thedrawings, the reference numeral 10 designates a suitable frame wherebythe various elements which form my improved typewriting machine aresupported in proper relationwith one another, the same havingupwardlyextending standards 11 atits' rear end which serve as supportsfor a rear carriage rail 12 which supports the rear end ofa travelingcarriage l3, and for an oscillating rod 14 to which two arms 15 and twomembers 15, for shift ing the platen 16 vertically into upper andlower-case positions, arese'cured'; the said platen being supported in aplaten frame having end plates 17, and the front end of the carriagehaving a roller which runs along a front rail 18 carried byupwardly-extending standards 19 at the front portion of the framework.The two arms 15 are located near the standards 11. A shift bar 20, alongwhich runs a roller 21 operatively connected 'with the cnd'plates 17 issupported at its ends by the members 15, which are located some distanceoutside of said arms 15. The arms 15 may be operated by upwardly eX-tending arms'22 at the rear ends of shift levers 23 pivotally supportedfrom a crossbar 24 located at therear end of the machine, and whichshift levers are provided withshift keys 25 at their forward ends andlocated 111 the keyboard of the machine, two such levers being employed,one engaging each of arms 15.

Supportedlb the. frame of the machine and preferably located neartherear end thereof is a guide shown .as comprising two guideways 26spaced'apart from one another and having eacha Vshaped groove as bestshown in Fig. 1. of the. drawings, and 27 designates a barhavingcorrespondingly V- shaped'grooves and which bar is movable betweenand longitudinally of the guides 26, suitable balls 28 being ordinarilyinterposed between'adjacent pairs of grooves'in order to reducefriction, as will be appreciated. The bar 27 is provided withforwardlyextending arms 29 located one at each end thereof and havingbearings at their free ends, and 30designates vertically-extendingshafts supported in said bearings, and the upper ends of which carryribbon spools 31 which support a ribbon 32. The lower ends of the shafts30 are provided with beveled gears 33 which mesh with beveled gears 34of the frame H p (The several type-sets upon a horizontally-arrangedribbon-feeding shaft 85, through which the vertical shafts 30 may beoperated to thereby wind the ribbon from one spool to the other,it'being understood that there is an arm 29 at each end of the bar 27,Fig. (i, and that a spool shaft 30 is supported in bearings provided atthe forward end of each arm, although only one of said arms is shown. V

The longitudinally slidable bar 27 also carries a plurality of pairs ofsupporting bracketsdtl extending forwardly therefrom, as many ofsuchpairs of brackets being provided asth'erc are type-sets orequivalent printing devices to be supported from the bar 27. ,In theembodiment of my invention illustrated, two printing devicesin the formof type-sets are provided and which are designated. as a whole by thereference numerals 37,, Fig. 3, although more than two print ing devicesmaybe provided for should it be deemed. necessary or desirable to do so,all of said devices being supported from the longitudinally movable bar27 and'moi able' therewith, as will be appreciated.

The type-sets 3? each comprise a type-bar supporting segment 38 whichcarries a plurality of type-bars 39 pivotally supported in slots 40formed therein, and two depending side portions 41, the lower ends ofwhich are connected with one another by a cross-bar 42, Fig. 3; said.cross-bar 42 being provided with a plurality of slots 43. within whichaplurality supported, one such lever being 'operatively connected witheach type-bar 39 through a pin-and-slot connection 45 at the upper endof said lever, as best shown in Figs. 1 and'S of the drawings;

37 are eachdetachably connected with the sliding bar '27 through and bymeans of the pairs of brackets 36 above mentioned, to which end thebrackets which form each pair are provided with slots 46, 47 and the endmembers 41 of. the type-sets with pins 48 adapted to enter the lowerslots 4-7 and. the upper slot 46 of the bracket'which supports the innerone of the side portions 41,Figs. 1 and 6.

The outer end members of the type-sets are provided each with a slidablespring-pressed locking member-49 having a beveled head 50 adapted to lieina correspondingly-shaped.

recess provided at the inner end of the upper slots 46 of the bracketswhich. support the outer end members 41, as best shown in Figs. 4- and6; whereby when a locking member 49 is forced inward the. beveled head50 thereof is moved out of the recess in which it normally lies, thuspermitting the type-set with which it is associated to be swung forward,upon the lower pair of pins 48, as shown in Fig. 8, and removed from thesupporting bar 27 and from the machine by lifting the pins 48 out of theslots 47'. Any

, type-set or all of them may be thus removed of a pawl 57, Figs. 1,

from the machine, and other type-sets difi ering as to the character orstyleof the type carried by them may then be substltuted for the setsremoved; or type-sets adapted to typewrite in a different language maybe substituted for those removed; a single machine bein capable ofoperating with any number or type-sets, as will be appreciated.

T he bar 27 is stead ied in its movements and binding between the sameand the guides 26 in which it moves, due to the-offset arrangement ofthe typesets and ribbon-supporting mechanism, which are ordinarilylocated to one side 01 the vertical plane of the barand guides, isreduced, by the use of brackets 51 carried by the said bar and extendingbelow the lower guide 26, and carrying rollers 52 at their lower ends;whiclrrollers move in contact with a stationary rod or guide 53supported from the frame oi the machineas the bar and the type-setscar.-

' ried thereby are shifted relatively to the frame of the machine.

The reference numerals 54-, see Fig. 7, designate two recesses ornotches formed in a rib extending from the rear side of the bar 27 andspaced apart from one another, the middle portion 55 of said rib beingof lesser height than the end portions 56 thereof, the purpose of thesaid notches being to lock the bar 27 in whichever one of the extremepositions into which it may be moved; the location of said notches beingsuch that when the bar is locked, as aforesaid, one or the other of thetype-sets carried thereby will be in proper position for typing upon awork-sheet carried by the platen 16. a position such that any one of thetype-sets The locking of the bar 27 in maybe used. may be accomplishedby means 7 and 9, movable into and out of the notches '54, said pawlbeing carried by a shaft 58, the ends of whichare journaledin the frameof the machine. S ecured to this shaft 58 is a depending arm 59, thelower end of which is pivotallycon nected with a link 60. The forwardend of this link 60 is pivotally connected with the lower end of a lever61 pivotally mounted'at 62 on the frame of the machine, and the upperend thereof extends into convenient position where it may be manipulatedby the operative, so that as the upper end of said lever is swungbackward on its pivotal support .62 motion will be commnnicatedto thepawl 57 throughthe shaft 58, and the free end of said'pawl will bemovedout ofwhichever one of the recesses 54 it may then he in, whereupon thebar 27 andtyp e-sets carried thereby may be moved sidewise along theguides 26 and itfilll'felGTlt type-set brought into position for use.

In shiftin'gfrom one to the other of the two type-sets, which at anygiventime may be supported and carried by thebar. 27, the

pawl 57 need be moved rearwardly only far enough to clear the lowermiddle jpor- \Vhen, however, it is desired to removeone of the type-setscarried by the bar, the pawl 57 is moved rearwardly to a greater extent-Fig. 9, and to an extent such that it will clear the higher endportions 56 of said rib. This permits the bar 27 to bemoved to a greaterextent than it is normally moved, as shown in dotted lines in; Fig. 6,and to an extent determined by a stop 56? which cooperates with the pawl57, so that thetypeset-to he removed will be cle'arof the forwardupwardly extending standards 19, whereupon the same may be released fromthe upper slots 46 in the brackets 36 and swung forward and removedpfromthemachine, as shown in Fig. 8, preparatory to substituting a differentstyle of type-set for the one removed. When desired, recesses or notches54 may also be provided in end p01 tions 56 adjacen'tstops56, so as toenable bar 27 to .be locked in position while typesets are beinginserted and removed.

Located within the space 63 of the frame of themachine ,is the keyboard,the same comprising a plurality of key-levers (34 having operatingkeys65 at their forward. free ends, and the rear ends of allysupportedffro'm the framelofthe machine in the slottedbar 24hereinbefore re} ferred to; springs 66, one foreach key-lever,

being provided in order to keep the same-in means are provided foroperatively connecting the set of key-levers with whichever one of theplurality of type-sets the operator may desire to use. The connectingmeans employed in the embodiment of my invention illustrated in thedrawings comprises a plurality of intermediate operating links 68,

one for each type-bar, the lower ends of said links being pivotallyconnected with the keylevers at 69, and the upper ends thereof beingoperatively and etachably connected with the type-bar operating levers44; to which end the said levers are providedwith forwardly-extendingportions provided with which are 'pivot-.

slots 70 into and out of which pins 71 carried by the connecting links68 may be moved. I i V Movement is imparted to the intermediateconnecting links 68 to move the pins 71' into bail 72 which lies inslots73 providedin the intermediate links;,the said bailibeing movableto thereby simultaneouslyswing all the said links about their pivotalconnections '69 and move the pins.;71- into and out of; gagement withthe slots 70. This bail72 is supported by an oscillatingshaft7-1supported in bearings provided in the frame of the machinebymeans of upwardly-extending arms 75 located one at each end thereof, andthe upperends of which arms carry said bail. One of the arms 75 isprovided with a forwardly extending portion 76, see Figs. 1, 3 and 9,having a headed pin 77 at its free end; which pin extends into a camslot :78 provided in the link through which the locking mechanism forthe bar 27- is operated. This slot 78 is of such a form as-to produce aforward movement of the bail 72 as the link 60 .is moved forward bymeans of the lever 61, which forward movementof the bail will swing theset of intermediate links 68' forwardlyabout their pivotal connections69; from which itfollows that as the lever 61 isswung upon its pivotalpoint 62, the pawl 57- will bemovedout of one of thenotches5t, and thepins 71 of the links 68 moved simultaneously out of the slots 7 0 of thetype-bar operating levers 44, thus disconnecting the key-levers from thetypeset whichthey have been connected with and freeing the bar 27, sothat the sameytogether with the type-sets carried thereby, maybe movedsidewise by a finger-piece 67 extending forwardly from the slide bar 27.This releasing movement disconnects; the key levers from the particulartype just pre viously in use, and permits anew type-set to be moved intoproper position forguse, whereupon, and as the lever 61 returns toitsoriginal position, the pins '71 will 'be moved back intoengagement'with the slots of the type-bar operating'levers44 of anothertype-set, and the pawl 57 will enter the second notch 54, thus lockingthe bar27- in position'such that thewsecond type-set is in position foruse; 7 1 H i w Supported by the frame of thermachin'e' is V a bracket 79which, serves as a support'for an escapement mechanism, 1 whereby i theV movement of. the carriage 13 for letter spacing is controlled,and-also as a support for meanswhereby said escapement mechanism .isoperated by alnd vfrom the type-set in use at a given time. .1 j

The escapement mechanism is illustrated as ofa common'e type used in thestandard {Underwood typewriter, and as comprising an escapementwheel 180connected (bytheusual :one-way pawls, not shown) with a pinion 81 inengagement with a rack 82 carried by the carriage, the carriage beingmoved by'a suitable spring drum, not shown,

and the step-by-step movement thereof being controlled by a pair of dogs83,84 carried byra dog-rocker 85 also supportedby the bracket 79.

The dog-rocker '85 is operated by anin ter mediate reciprocatingoperating member 86 having a bar 87 which engages the: dogrocker .85,and which member is supported by a link 88,the ends of which "arepivotally connected therewith and with the bracket 79, and'by spacedupwardly-extending arms '89, of .arocker 90 also supported fromth'e saidbracket; said rocker having a depending arm 91, the free end of which isslotted, as at 92, and moves in slidingengagement with a bail 93 carriedat the free ends of arms 94 located at the ends of an oscillatingribbon-feeding shaft 95, Figs. '1 and '2, supported in ears 96 shown asdepending from 'two or 'more of the type-set supporting brackets 36. Ittherefore follows that the ribbonfeeding shaft 95 partakes of thelongitudin al movement with the bar 27 ,"and that the, said shaft isoperated from and by the intermediate reciprocating member 86 throughthe rocker 90, arm 91, and slotted end 92 thereof; the slidingengagement between the slot 92 and the bail 93 providing 5 a permanentoperating connection through which oscillating'movement is imparted tothe ribbon-feed shaft 95; I This ribbon-feed shaft carries pawls 97which engage the toothed'periphery of a ratchet wheel 98 carried by theribbon shaft 35 hereinbefore rc.

ferred to, whereby oscillatory motion imparted to the ribbon-feed shaft95 is com-- municated to the shaft 35 and rotates the same to wind theribbon 32 upon one or the other of'the ribbon spools31. 1

The machine may be provided with? a space-bar ear'riedby levers, therearendsof which are pivotally supported inthe cross-"- bar 24:, whichlevers will be operatively connected with an upwardly-extending armadapted to-engage the arm' 91 depending from the rocker 90, to therebyoperate the escapement independently of the key-levers, thesame asinmyco-pending case hereinbefore referred to, although these elements arenot shown in'the drawings;

Suitable ribbon-vibrating mechanism is provided, the samebeing supportedfrom the shift rail 20, whereby the platen is shifted, so as: to partakeof the vertical movements of the platen'as it'is shifted'into its upperand lower-case positions, the construction of which mechanism. is asfollows.

r Y removed to its replacement position, is out I Thereference numeral99 designates two arms carried on-the shift rail 20, and which armsserve as supports for the ends of a rod 10 0,which rod in turn carriestwo vibratlng 'members in the form of bell-crank levers 101, one suchlever being provided for each I type-set, although one only of them isshown; which levers slide along the rod 100 as the bar 27 is moved tobring either typeset into position for use. The verticallyextending armsof these bell-crank'levers 101 are provided each with apin 102, eitherof which pins may be moved into engagement with a slot 103, provided inan-upwardly-extending arm carried by the inter:-

porting segments 38 thereof; and in orderto provlde a separableoperating connection between the said levers and the vibrating members104, the aforesaid areprovided each with a slot 105, into which slotspins 106, carried at the lower ondsof the ribbonvibrating members 104,maybe moved, as will be understood-from Fig. 8; this detachable drivingconnection being provided in order that each type-set may be, moved outof operative relation with "the ribbon-vibrating lever 10lwith whichitis associated in removing the type-set from the machine.

It will be understood that the interme i diate actuating member 86 islocated at the .middle of-the machine, and that the ribbonvibratorlevers 101 are movable sidewise and relatively to said intermediatewactuatlng 'member 86 whenthe slide bar 27 is moved'to bring anothertype-set into eifectivere'lation with the keys. It will also beunderstood that anradditional sidewise movement is given to the slidebar 27 when itis desired to detachone of the type-sets so that it'may be:replaced by another When this addi-.

'tional movement is imparted to the slide bar 27, it will be seen thatthe ribbon vibrator lever 101,.associated with the type-set being ofengagement with the intermediate actuatmg member 86 and-to onesidethereof: To

prevent the ribbon-vibrator lever from.

swinging about the bar 100-at this time, or,

in other words, to guard against the pin 102 from co mingout ofalinement with the slot 103, so as to ascertain proper reengagementtherebetween, the ribbon-vibratinglev i universal bars,

provided with finger 101--"which rests against the shift rail 20, F ig;8.

The ribbon-vibrating levers 101 move vertically with the platen becauseof thefact that they are carried by the rod 100 which, asexplained, iscarried by the shift rail 20,

during the movement of which the ribbonvibrating members 10 1 follow theplaten, because of their connection with the levers 101 so that theribbon is maintained in proper position relative to the platen as theplaten is shifted, and when the same is in both its upper'and lower-casepositions. When the platen is in either of these POSI- tions, the ribbonis moved up simultaneously with the movement of a type-bar toward theplaten, because of the engagement. of a pin 102 in the slot 103 in thereciprocating inter- ;mediate member 86, which is operated by thetypeset-in use; the movement of said mem- 101, associated with thetype-set in use upon the rod 100, and thus shift the ribbon into thepath of the type, when the platen is'in eitherits upper or lower-casepositions The free forward end of each ribbon-vibrating lever 101 isguided in its vertical movements by guides 107, carried one by each ofthe type-bar segments 38, which guides,'because ber serving to rock theribbon-vibrating'lever of their engagement with the levers 1101, act

to slide the latter along on the rod 100, whereby they are supported,as-the'bar 27 is moved to bring a type-set into position for use, andserve also' to steady the for'ward endsoffth'e shifting levers andmaintain them in proper relation with the ribbonvibrating rnernbers 1041operated by" them. The reference numeral 108 designates a universal bar,Figs. 1 and 5, one bar being provided for each of the'type-sets, and thesame beingsegmental in form and operating in curved slots provided intherear faces of the type-bar supporting segments 38. These universal barsareengaged by the type-bars and moved rearwardly as thetype-barsapp'roach the :printing'point, which movement is-transmitted-to the intermediate member 86, to thereby operatetheescapementme'chanisni'; to which end ea'ch universal bar is providedwitha cross-bar 109,'1ocated in-line' with and adapted to engage thefree forward end of saidiintermediate member 101;"Each universal bar-"is guidedand'-' maintained parallel in its movement by means of arockshaft 110, supported in'lugs 111,"eXtending" from the rear face of-'the' segment 38, and which shaft carriesftwo arm's 112 located oneateach 'end thereof, as best showniinFig. 5,

It therefore follows that as theuniversal moves rearward-1y, it is maintained parallel with itself inall positions, because of the bell-crank lever 115 and arms 112 and114', which, in effect, provide two bell-crank levers, the shorter armsof which are connected together through the ment between each type-setand said set of key-levers,,so as t'obring any selected typeset and theset of key-levers into position to cooperate wlth each other, and meanswhereby said key-levers may be connected with or disconnected from theselected type'set while the latter is in cooperative relation therewith.
